Cannot replicate error between local and remote machine

Using Django Mystery Errors
1

I have code on my laptop that works fine, but when I migrate it to my nginx/gunicorn system, I get error “cannot unpack non-iterable NoneType object”. On the form, there are several input choices originating from models. Those work fine. There are two inputchoices that rely on dict and they seem to be the culprit. If I remove them from the template, there are no errors.

def search_plant(request):
    has_filter = False
    if not request.GET:
        data = models.PlantProfile.objects.none()
    else:
        data = models.PlantProfile.objects.all().order_by("latin_name")
        has_filter = True
    search_filter = filters.PlantProfileFilter(request.GET, queryset=data)
    object_list = search_filter.qs.annotate( #this subquery is from Ken
        is_owner=Coalesce( 
            Subquery(
                models.PlantCollection.objects.filter(owner=request.user, plants=OuterRef("pk"))
                .annotate(owns=Value("Yes"))
                .values("owns")
            ),
            Value("No"),
        )
    )
    return render(
        request,
        "project/search-plant.html",
        {
            "filter": search_filter, #No error if I comment this.
            "object_list": object_list,
            "has_filter": has_filter,
            "url_name": "search-plant",
            "title": "Plant Profile Filter",
        },
    )

Problematic filters:

    bloom_start = django_filters.ChoiceFilter(
        choices=utils.MONTHS,
        method="filter_gte",
    )
    bloom_end = django_filters.ChoiceFilter(
        choices=utils.MONTHS,
        method="filter_lte",
    )
    harvesting_start = django_filters.ChoiceFilter(
        choices=utils.MONTHS,
        method="filter_gte",
    )
    harvesting_end = django_filters.ChoiceFilter(
        choices=utils.MONTHS,
        method="filter_lte",
    )

utils.MONTHS is just a dict

MONTHS = {
    None: "",
    1: "January",
    2: "February",
    3: "March",
    4: "April",
    5: "May",
    6: "June",
    7: "July",
    8: "August",
    9: "September",
    10: "October",
    11: "November",
    12: "December",
}

It’s a nightmare to troubleshoot this on remote server and I simply wish I could get the error on my local machine.

The error is caused by something with the {{filter.form.light_to}} which appear to be non-iterable

            <div class="flex-col">
                <div class="title">Sun Requirement</div>
                <div class="light-range__inputs">
                    <div class="form__field"><label class="form-label">Max</label>{{filter.form.light_from}}</div>
                    <div class="form__field"><label class="form-label">Min</label>{{filter.form.light_to}}</div>
                </div>
            </div>

Can you provide the full stack trace, not just that bit of the error?

Sure, here it is.
Now I wonder if it could be a Django version issue. My local machine is on Django 5.1.3

Side note: Just like with the code, you need to enclose the tracebacks between lines of ``` to ensure all the data is being shown.

Oups. I saw you did it. Thanks.

6

Given that you’re running different versions of Django and Python between the two environments, have you ensured that all your ancillary libraries (such as django_filters) are compatible in your remote environment?

(You mention you’re using Django 5.1.3 locally, which implies at least Python 3.10. But your remote system is Django 4.2 & Python 3.9, which could cause some version incompatibilities with other third-party libraries.)

Also, I noticed you’ve got django.forms in your INSTALLED_APPS. I’m not aware of any situation where it is used as a Django app - you might want to remove it.

7

Well, I recreated my venv on the remote computer using python 3.12, which I had to compile first, upgraded django to 5.1 and everything is working fine. Wonderful Python/django.

Will check what this django.forms is doing in the INSTALLED_APPS

8

I don’t know how many third-party packages you are using in your project, or how you’re building your environment in that remote system, but it might have been less work to first check the versions of the libraries you are using.

9

Going back to the django.forms in my INSTALLED_APPS, if I remove the statement, I get a TEmplateDoesNotExist error. But that might be off topic.

Also, I am using django_filters but I don’t need to have it in my INSTALLED_APPS which I find strange since it should be there according to Installation - django-filter 24.3 documentation

What happens if you have django_filters in INSTALLED_APPS but not django.forms?

11

Still get template does not exists with following:

INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "django.contrib.staticfiles",
    "django_filters",
    # "django.forms",
    # "debug_toolbar",
    "django_browser_reload",
    "project",
]
12

What is your TEMPLATES setting from your settings file?

13 
TEMPLATES = [
    {
        "BACKEND": "django.template.backends.django.DjangoTemplates",
        "DIRS": [BASE_DIR / "templates"],
        "APP_DIRS": True,
        "OPTIONS": {
            "context_processors": [
                "django.template.context_processors.debug",
                "django.template.context_processors.request",
                "django.contrib.auth.context_processors.auth",
                "django.contrib.messages.context_processors.messages",
            ],
        },
    },
